Abstract

1377601 Semi-conductor devices SIGNETICS CORP 6 March 1973 [27 March 1972] 10881/73 Heading H1K A semi-conductor body 21 of, e.g. doped silicon having one conductivity type is diffused or ion implanted with dish shaped regions of opposite conductivity extending to its planar surface to define emitter and collector regions with the body as base, and diode or resistor regions forming part of an integrated circuit. An insulant layer 23 of, e.g. thermally grown SiO 2 is formed on the surface in which windows are opened to expose the surface on to which metal, e.g. Al is evaporated to contact the several regions. The metal is removed using photolitho masking to leave adherent leads integral with Al pads 26 spaced round the periphery of the body; the leads extending inwardly from the pads to contact the several regions of the device. A glass layer 28 is deposited over the SiO 2 layer and the leads, in which windows are opened to expose portions of the pads by photoresist masking and etching with HF + ethylene glycol + H 2 O, after which the photoresist is removed. After alloying thermally, a further layer 31 of, e.g. Al is deposited on the glass layer to extend into the openings, and a layer 32 of, e.g. Cr is evaporated thereon as a barrier. A layer 33 of, e.g. Ni is deposited on the Cr by evaporation (Fig. 5). A photoresist mask with windows overlying the pads 26 and their openings is formed on Ni layer 33, and stand off pillars 37 of, e.g. Ni are formed therein, e.g. by electroplating to serve as spacers between the surface and the external leads. A layer 38 of, e.g. Au, a layer 39 of, e.g. Sn, and a further layer 41 of, e.g. Au are electroplated in sequence on the pillars, and the photoresist is removed by solution. A further photoresist layer 43 is formed over the structure (Fig. 12) to underlie the head of the pillars, is baked and is selectively exposed to light, so that after development and solution a band of photoresist remains underlying the pillar head to protect the exposed Sn and Ni layers. The exposed parts of the Ni and Cr layers 33, 32 are electrolytically etched out in H 3 PO 4 with the semi-conductor body as anode, and the exposed Al layer 31 is removed by etching in hot H 3 PO 4 with a foaming agent to limit undercutting. The photoresist band is removed by solvent and the complete device (Fig. 16) is washed and dried. Plural discrete standoffs are connected to pads 26 of the interconnecting leads of the integrated circuit (Fig. 17, not shown). The device is bondable to lead frames of the kind described in Specification 1,359,698 fabricated of Sn plated steel by opposing the frame to the tops of the standoffs in proper alignment and soldering with a gas jet, (Fig. 18, not shown). The assembly may be plastic encapsulated as described in Specification 1,359,698, or enclosed in a package of glass or ceramic.
